General Description
Photonics of Crystals (POC) Photoelastic Modulators (PEM) are state-of-the-art modulation devices designed to alter the polarization state of light by introducing a dynamic phase retardation to transmitted light. Utilizing isotropic materials, PEMs operate at inherent resonant frequencies, leveraging the photoelastic effect to achieve periodic refractive index changes that influence the retardation of incident light.
POC’s PEMs stand out for their high modulation frequency, large acceptance angle, and superior precision, making them ideal for demanding optical applications. Available in one-dimensional and two-dimensional configurations, these modulators cater to diverse requirements: one-dimensional PEMs are optimal for UV, visible, and near-infrared applications, while two-dimensional PEMs enable broader phase modulation capabilities across visible and infrared bands.
The innovative design of POC’s PEMs ensures accurate phase control, reduced crosstalk, and high throughput, positioning them as a reliable choice for advanced optical systems. Their high-quality construction supports seamless integration into various setups, delivering consistent and precise modulation.
